RACO RACO126 – Frequently Asked Questions
1) Does the RACO 126 octagon box come with a mounting bracket, or do I need to support it separately?
No bracket. The RACO 126 ships as a plain 4 in. octagon box, so it has to be supported by the conduit run itself or by a separate bar hanger or box support. If you need a bracket-mounted box for stud framing, pick a bracketed octagon instead.
2) What size conduit can I land on a RACO 4 in. octagon box 126?
Knockouts are two 1/2 in. and six 3/4 in., so you can bring in 1/2 in. or 3/4 in. trade size conduit, and the six 3/4 in. openings let you feed from several directions on a through-junction. Larger trade sizes are not accommodated without a reducing arrangement.
3) Is the RACO 126 suitable for NM cable, or conduit only?
It's built for conduit wiring systems. The box has knockouts rather than cable clamps, so for nonmetallic sheathed cable you'd need to add listed cable connectors in the knockouts or choose a box supplied with NM clamps.
4) How deep is the RACO 126 octagon box, and will it take a few splices plus a fixture whip?
Depth is 1-1/2 in., the deeper of the two common drawn octagon depths, which gives you room for conduit entries plus splices without packing the box. For heavy multi-circuit splicing you'd move up to a 4 in. square or an extension ring.
5) Drawn versus welded steel octagon box, which should I spec?
The 126 is drawn, meaning the body is formed from one piece with no weld seams. That gives a smooth continuous enclosure with no seam to split when you're knocking out openings or torquing connectors. Welded boxes are the alternative construction and are typically chosen where a deeper or non-standard box shape is needed.
6) Is the RACO 126 UL Listed for commercial work?
UL Listed, and it's intended for both residential and commercial conduit installations, so it will satisfy an inspector looking for a listed outlet or junction box on a commercial fit-out.
7) Will a standard 4 inch octagon cover or ceiling fixture pan fit the RACO 126?
Yes. It's a 4 in. octagon box, the standard trade size, so 4 in. octagon blank covers, round covers and fixture canopies with the usual octagon screw spacing land on it. The cover is a separate order.
8) What does the raised ground on the RACO 126 do for me?
It gives you a built-in raised boss for the equipment grounding screw, so you bond pigtails and the fixture ground straight to the box without hunting for a tapped hole or adding a ground clip.
9) What is the exact manufacturer part number for this RACO octagon box?
RACO part number 126. It's the 4 in. drawn steel octagon, 1-1/2 in. deep, raised ground, no bracket.
